When that returns, restore state and resume. i was only thinking of an arm7 kernel handling arm5 executables so no emulation should be needed. so like for NEON now, a NEON program wont work on hardware without NEON. i assume the arm5 instruction set is upward compatible so it would seem even easier than an existing x86_64 kernel running 32bit code which is not binary compatible. are you sure the fp arg style is a kernel issue? are there system calls that take floats (not in structs or arrays but as a single argument)? i could be totally wrong. it just seems almost there... _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
